Slurry shield full-automatic pipe replacement crane

Abstract

Disclosed is a slurry shield full-automatic pipe replacement crane. The slurry shield full-automatic pipe replacement crane comprises a trailer and a pipe replacement crane mechanism. The pipe replacement crane mechanism is installed on the trailer, and a pipe storage mechanism is arranged on the trailer. The pipe replacement crane mechanism comprises a pipe replacement crane longitudinal beam, wherein the pipe replacement crane longitudinal beam is connected with the trailer. A longitudinal translation oil cylinder is arranged on the pipe replacement crane longitudinal beam, and a travelling frame is connected to the stretching and drawing end of the longitudinal translation oil cylinder. A crane transverse beam frame and a transverse translation oil cylinder are arranged on the travelling frame, one end of the transverse translation oil cylinder is connected with the crane transverse beam frame, and the other end of the transverse translation oil cylinder is connected with the travelling frame. An electric hoist is arranged on the crane transverse beam frame, and moves along the crane transverse beam frame. A tank chain groove is formed in the top of the travelling frame, a tank chain groove is also installed in the lower surface of a platform on the top of the trailer, and the two tank chain grooves are connected through a tank chain. The slurry shield full-automatic pipe replacement crane is simple in structure and high in practicability, is successfully put into use, reduces the labor intensity of workers in the slurry pipe replacement process, and greatly improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for a shield machine, in particular to a fully automatic pipe changing crane for a muddy water shield machine. Background technique [0002] Common mud-water shield pipe changing devices have a pipe changing crane device, the purpose of which is to reduce the labor intensity of personnel and improve work efficiency during the extension of the mud pipeline in the tunnel to the mud pipe. Although the forms of mud-water shield tube replacement cranes designed by various shield machine manufacturers are different, most of them are semi-automatic cranes, which can only realize the automation of mud tube transfer or hoisting functions, and there are certain limitations in use. . The staff of the existing pipe changing crane has high labor intensity, low work efficiency, and low operating safety factor. Therefore, it is necessary to design a fully automatic pipe changing crane. Contents o...
